I also see Sharp-shins feeding at my feeders regularly. Once I was fixing
the sheetrock in the ceiling of my garage when a sharp-shin chased a
towhee into the garage, around the latter, and back out. Also, on a snowy
winter a couple of years back there was a curious association between a
northern pygmy owl hanging about and neat little piles of yellow evening
grosbeak feathers on the snow. (Seemed like a pretty big target for that
little fellow to me.)
